Hey mate here is your answer :::
Total no. of students :::
60% of X = 18
60/100x = 18
X= 18*10/6
X= 30
No of girls = 18
No of boys = 30-18 = 12
Ratio will be 18/12 = 18:12 = 3:2
Hope it helps you Mate ☺️

Answer:
Step-by-step explanation:
Let x be the total number of students in the class.
60% of x = ? (number of girls)
40% of x = 18 ( number of boys)
therefore, (2/5)x=18
x=45 ( Total number of students)
hence, number of girls = 27
